OSCILLA is an interactive installation that explores harmonic structures and their visualization by enabling ‘musical’ interplay within a responsive audio-visual environment.

A projected scalable interface allows for context-specific adaptability and for a variety of intuitive physical interaction paradigms whereby the positions and movements of people or objects, optically tracked within a given area, determine the volume and pitch of a set of sine-wave oscillators.

Each position and frequency value is projected on the main surface, along with music notation, while a graphical representation based on Lissajous figures shows the correlation between frequencies and amplitudes of the sounds in real time, generating shapes and patterns the complexity and regularity of which is directly related to the 'musicality' of the mathematical relationships in the chord being played.

The oscillators' outputs, when discretely amplified by multiple loudspeakers, also provide different auditory spatial perspectives into each harmonic structure, while enhancing natural acoustics and resonances of the installation space.

Inspired by the 'Oscilla', votive objects of the Latin tradition, the installation can also be experienced as a sort of modern and technological ritual/game to explore the fascinating harmonic laws behind our perception and understanding of sound.
